Buying the best PSU goes beyond checking the wattage. An 80 Plus Gold PSU assures high power efficiency and savings.
The right PSU can go a long way to ensure your system runs optimally. While performance is one important factor, efficiency is another. The right combination of both gives you the best system experience as well as lower power costs. A good efficiency rating also ensures that less heat is generated while delivering the required power. This also improves the thermals of your system. An 80 Plus Gold rating for your PSU means an efficiency of 87% at 20% load, 90% at 50% load, and 87% at 100% load. To pick the right one for your system, here are some options available on Amazon that pack a good combination of specifications and features.
